BigWig support for genomicProfiles view

[keller-mark]

Fixes #1431

Background

TODO

• make PR for changes in https://github.com/keller-mark/higlass-bigwig-datafetcher back into higlass/higlass-bigwig-datafetcher, then use new version of higlass/higlass-bigwig-datafetcher here
• add Vitessce fileType to reflect this
• add bigwig to docs as a supported fileType
• implement FileType.GENOMIC_PROFILES_ZARR as a joint file type (mapping each multivec "row" to an atomic file type to match the bigwig case)

Change List
